The number of applications of interval type-2
fuzzy logic to real world problems is growing. To date such
systems have used type-reduction or an approximation of typereduction
to arrive at final crisp output from the system.
This paper describes the novel direct defuzzifier for interval
type-2 fuzzy sets. A number of fuzzy systems are compared
with direct defuzzifier. We compare each defuzzifiers output
surface in a simple rule-based system. The direct defuzzifier
compares favourably with the type-reduction method under
the minimum t-norm. Also, we found that the non-stationary
approach provided interesting results.
